WILLIAM F. MARKHAM, OF PLYMOUTH, MICHIGAN, ASSIGNOR TO THE MARKHAM AIR RIFLE COMPANY, OF PLYMOUTH, MICHIGAN, A CORPORATION OF MICHIGAN.

AIR-GUN.

Specification of Letters Patent.

Patented July 23, 1907.

Application filed June 30, 1906- Serial No. 324,290-

To all whom it may concern:

Be it known that I, WILLIAM F. hIARKHAM, a citizen of the United States of America, residing at Plymouth, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Air-Guns, of which the following is a specification, reference being had therein to the accompanying drawings.

It is the object of the invention to obtain a simple and inexpensive construction of gun that is particularly adapted for a toy pistol or pop gun.

The invention consists in certain novel features of construction as hereinafter set forth.

In the drawings, Figure 1 is a section elevation of the gun; Fig. 2 is an enlarged longitudinal section through a portion of the barrel; Fig. 3 is a cross section on I line :c:c, Fig. 2; and Fig. 4 is a section on line y y,

Fig. 2.

The barrel A is preferably formed of a cold shut tube formed from sheet metal, and at its breech end is provided with a sheet metal frame piece B preferably soldered thereto. To this frame piece the stock 0 pivoted by a belt or pin D, and a trigger E is also pivoted therein.

The stock 0 is formed of a sheet metal member a.

for closing the breech of the barrel and overlapping the ears I), which project rearwardly from the frame piece B. The rear portion of the stock is formed of a rod, or wire, 0 having one end soldered in the bend ofthe sheet metal piece a, and its opposite end bent into an eye d which surrounds the pivot pin D. Thus the eye d forms a reinforcement for the pivoted bearing in the sheet metal member a and is embraced by the ears I).

In the forward portion of the barrel A is a shorter barrel E which forms the air compression cylinder. This barrel E is also preferably formed of a cold shut tube telescoping within the tube A and turned to have its seam on the opposite side from that of the outer barrel. The piston abutment is arranged at the outer end of the two barrels and is formed by a pair of reversely arranged double sheet metal eyelets. These eyelets are secured in position, and the barrel E is also secured to the outer barrel A by sweating with solder.

The piston comprises a rod, or Wire, G at the outer end of which is secured a piston head composed of a leather washer H and a pair of smaller reinforcing metallic washers I and I on opposite sides thereof. These parts are secured to the rod by sweating on the latter a sheet metal collar .I, which forms a shoulder against which the washer I abuts, while the end of the rod G is riveted over the washer I.

The spring K is sleeved over the rod G, and is positioned by the collar .I. The forward end of this spring bears directly against the piston head, while its rear end is anchored by a thimble L formed of sheet metal inserted within the barrel A and anchored by an outwardly extending lip, or tongue, M engaging an aperture N in the barrel.

Where the gun is used for shooting a cork, such as 0, this is seated in the bearing formed by the eyelets F, and may be attached by a string or flexible connection P to the frame member B.

What I claim as my invention is:

1. In an air gun, a piston comprising a rod, a collar soldered thereon and forming a shoulder, a pair of metallic washers, and an intermediate leather washer sleeved on said rod abutting against said collar, the outer end of said rod being riveted over the outer washer.

2. In an air gun, the combination with a barrel and a piston therein, of a piston abutment formed by sheet metal eyelets fitting within and secured to said barrel.

3. In an air gun, the combination with a barrel, and a piston therein, of a combined piston abutment and bushing formed of sheet metal eyelets fitting within the barrel at its outer end and secured thereto by solder.

I. In an air gun, the combination with a barrel and a piston therein, of a combined piston abutment and bushing comprising a pair of oppositely turned sheet metal eyelets inserted in the outer end of the barrel and secured thereto by solder.

5. In an air gun, the combination with a barrel having a lateral aperture and a spring in said barrel, of a sheet metal thimble forming a spring abutment and provided with a lip engaging said lateral aperture.

6. In an air gun, the combination with a barrel and a spring therein, of a spring abutment comprising a sheet metal thimble having one end turned inward for a bearing for the spring and a lip projecting from the opposite end 90 of said thimble engaging an aperture in the barrel.

7. In an air gun, the combination with a barrel and a spring therein, of a spring abutment comprising a sheet metal thimhle having one end turned inward for a bearing for the spring, and a lip projecting from the opposite end 95 of said thimble engaging an aperture in the barrel.

8. In a toy gun, a stock formed of a sheet metal member at the breech of the barrel, and a bent wire member having one end soldered to said sheet metal member, the opposite end bent into an eye and a pivot pin engaging said eye 100 and said sheet metal member.

In testimony whereof I aflix my signature in presence of two witnesses.
